McFarlane Aviation FAA-PMA replacement seat parts were developed to assist in complying with the parts replacement requirements of A.D. 2011-10-09. This A.D. requires the periodic inspection and replacement of the seat components of the entire Cessna light aircraft fleet. Our parts are direct replacements for the wear related seat components. For convenient tools to inspect your seat rails per this AD, see the GAUGE SR1 seat rail wear gauge and TOOL110 seat roller housing gauge.
McFarlane seat parts are superior to O.E.M. parts in many ways. Our rollers are fabricated from molydisulfide filled nylon for improved strength and self-lubrication. All rollers are fully machined from extruded stock for a finer surface finish and higher strength. McFarlane bushings are machined from alloy steel for longer life and greater wear resistance. Our wear washers are made from a super tough acetyl plastic and have far better wear properties and resistance to aging. McFarlane seat components will outlast the original parts.
The seat related replacement parts are not serial number specific as the type of seat installed in the aircraft was optional when the aircraft was ordered from the factory. A common seat configuration is the pilot seat being articulating while the co-pilot seat is the standard or vertically adjustable style.
The best way to ensure that you are choosing the proper seat kit for your aircraft is to measure the rollers:
- Articulating seats and model 177 Cardinal seats use the MCS1704-1 roller (approximately 1 3/8 diameter)
- Standard seats use the MCS1551-1 roller (approximately 5/8 diameter)
- 150-152 Series and pre-1963 single engine Cessna aircraft use the MC0311310 roller (approximately 7/8 diameter with no wear washers)
- Obsolete roller 1964-1965: Cessna aircraft manufactured in 1964 and 1965 had a spool shape roller with a smaller bushing. Use SEAT-KT-2 to replace this style roller. The complete kit must be used, as the bushing size is different.
